Nissan 510 front turn signal bulbs measure 1157 in size, while rear turn signal bulbs measure 1156, with each bulb type serving distinct lighting functions on the vehicle. The replacement chart covers 1968 to 1981 production years and contains bulb size specifications for turn signal applications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Nissan 510 uses the 1157 bulb for the front turn signal across all listed model years, spanning 1968-1973 and 1978-1981.
The 1157 is a dual-filament bulb, meaning it serves two lighting functions within a single housing, operating at 12 volts with filament ratings of 21W and 5W.
The 1157 uses a BAY15d bayonet base, which features two offset pins at different heights to prevent incorrect installation of the bulb into the socket.
The Nissan 510 rear turn signal takes the 1156 bulb across the same model year range, 1968-1973 and 1978-1981.
The 1156 is a single-filament bulb rated at 12 volts and 21W, making it dedicated to one lighting function rather than the dual role of the 1157.
The 1156 uses a BA15s bayonet base, which has two pins at equal heights, distinguishing it physically from the BAY15d base of the 1157.
Although the 1156 and 1157 share a similar 15mm bayonet base width, their pin configurations differ, and the two bulbs are not interchangeable between front and rear sockets.
Both the 1157 and 1156 are ANSI-standardized bulbs recognized in the United States and Canada, indicating consistent electrical and physical specifications across manufacturers.
